> when riseup.net got an NSL to give access to the email accounts
This is simply not true. An NSL cannot be used to compel access to any communication content—and certainly not control of an account; they're limited solely to metadata (e.g. phone call records, IP addresses, billing metadata, etc.). I'm not a fan of NSLs, and strongly support repealing the section 505 expansion, but it behooves no one to lie about what an NSL is and what it can compel.
